Spectrofluorimetric-based Approach to Screen Urine Contamination in Drinking Water: A Step Toward the Development of Screening Method for Leptospirosis. Indian Journal of Public Health. 2022 Dec; 66(4): 487-4890019-557X2229-7693http://imsear.searo.who.int/handle/123456789/223871Hygiene hypothesis and sanitization are two important pivots of modern civilization. The drinking water should be free from urine and stool contamination. Coliform test is popular for understanding feces contamination. However, understanding urine contamination in drinking water is a difficult task. On the other hand, urine contamination can cause disease like leptospirosis. It occurs mainly in animals and infects humans through contaminated water, food, and soil and causes serious consequences. Rat urine is the most common source of such disease outbreaks. Further, sophisticated laboratories with high-end technologies may not be present at the site of disease outbreaks. In this context, we have proposed a spectrofluorimetric approach to screen urine contamination in water. The screening method can sense up to 156 nl/ml of rat urine2?naphtholfluorescenceleptospirosispublic healthrat urinewater contaminationJournal ArticleIndiaSenior DemonstratorPhD StudentResearch AssociateTutor (Bioinformatics)Professor, Department of Experimental Medicine and Biotechnology, PGIMER, Chandigarh, India
